Using the MSP-144 magnetic analyzer structure and stability of very neutron-rich nuclei of the lightest elements (7-10He, 9-11Li, 12-14Be) as well as of their heavy isotopes were studied and binding energy of the latter determined. The data on 7,8,9He, 10,11Li, and 13Be nuclei energy levels were obtained for the first time.

6He and 9Li secondary beams of 104 s-1 intensity were produced and used in the first experiments for measuring angular distributions of the 6He and 9Li ions
elastically scattered from various target nuclei. Data on interaction radii of these
nuclei were obtained for the first time. Later experiments on measurement
of excitation functions for complete fusion reactions with subsequent evaporation
of neutrons and fission in a wide energy range (10-70 MeV) were carried out with
6He beams of the DRIBs acceleration complex using the MSP-144 spectrometer.
The results of these experiments for the first time indicated the possibility of deep
sub-barrier fusion of 6He (neutron halo nucleus) with other heavy nuclei.

In 2018 MAVR new magnetic analyzer based on the the MSP-144 spectrometer magnet is to be put into operation. That with upgraded U400R cyclotron and DRIBs III acceleration complex beams of radioactive nuclei rise studies of nuclear reaction characteristics to the new higher experimental level.
